Chinese Chemical Letters 2024年第7期35卷 281-284页

Herein, we report the first visible-light photoredox-catalyzed carboxylation of aryl epoxides with CO_(2)to synthesize hydroxy acid derivatives. A variety of valuable β-, γ-, δ-, ε–hydroxy acid derivatives are obtained in moderate to high yields under mild conditions. This protocol shows noteworthy functionalgroup compatibility, high chemo-and regioselectivities under transition-metal-free conditions with an inexpensive organo-dye as photosensitizer. Mechanistic studies indicate that the benzylic carbanion is generated as an intermediate via the sequential single electron transfer(SSET) process.

Protective effects of ischaemic postconditioning on warm/cold ischaemic reperfusion injury in rat liver： a comparative study with ischaemic preconditioning

引用

Chinese Medical Journal 2008年第20期121卷 2004-2009页

作者： WANG Ke-xin HU San-yuan jiang xu-sheng ZHU Min JIN Bin ZHANG Guang-yong CHEN Bo Department of General Surgery Qilu Hospital Shandong University Jinan Shandong 250012 China

Background Ischaemic reperfusion injury （IRI） is inevitable during major liver surgery. Ischaemic preconditioning （IPC） has been proven an effective intervention against hepatic IRI. Recently, it was demonstrated that ischaemic postconditioning （IPO） provided effective cardioprotection on IRI. We evaluated the protective effects of IPO on warm/cold IRI in rat liver by a comparison with IPC and assessed the role of apoptosis in the process.Methods Warm IRI model （clamping hepatic pedicle for 30 minutes） and cold IRI model （orthotopic liver transplantation with 2 hours cold storage） were established. Each model consisted of 3 groups：（1） control group, normal warm/cold IRI; （2） IPC group, 5 minutes of ischaemia followed by 5 minutes of reperfusion twice prior to warm/cold IRI; （3） IPO group, 30 seconds of reperfusion followed by 30 seconds of reocclusion for three times after warm/cold ischaemia. The levels of serum transaminase, glucose, and γ glutamyltransferase （GGT） in bile, histopathological examination, apoptotic activity of hepatocyte, and apoptosis related protein Fas, at 3 hours after operation were compared. Survival rates one week after intervention were also compared.Results IPO and IPC protected the functions of hepatocytes and biliary epithelial cells, inhibited the hepatocellular apoptosis by preventing expression of Fas gene, and elevated the one week survival rate compared with control group in both models （P 〈0.05）. IPO and IPC groups were comparable in levels of serum transaminase levels, glucose, and GGT in bile, Fas positive expression index, and one week survival. In cold ischaemic models, IPO had lower apoptotic index than IPC （P 〈0.05）.Conclusion Compared with ischaemic preconditioning, ischaemic postconditioning is associated with comparable protections of rat liver from warm or cold ischaemic reperfusion injury.

Exploration of Gas-Dependent Self-Adaptive Reconstruction Behavior of Cu₂O for Electrochemical CO₂ Conversion to Multi-Carbon Products

Structural reconstruction of electrocatalysts plays a pivotal role in catalytic performances for CO2 reduction reaction (CO2RR), whereas the behavior is by far superficially understood. Here, we report that CO2 accessibility results in a universal self-adaptive structural reconstruction from Cu2O to Cu@CuxO composites, ending with feeding gas-dependent microstructures and catalytic performances. The CO2-rich atmosphere favors reconstruction for CO2RR, whereas the CO2-deficient one prefers that for hydrogen evolution reaction. With the assistance of spectroscopic analysis and theoretical calculations, we uncover a CO2-induced passivation behavior by identifying a reduction-resistant but catalytic active Cu(I)-rich amorphous layer stabilized by *CO intermediates. Additionally, we find extra CO production is indispensable for the robust production of C2H4. An inverse correlation between durability and FECO/FEC2H4 is disclosed, suggesting that the self-stabilization process involving the absorption of *CO intermediates on Cu(I) sites is essential for durable electrolysis. Guided by this insight, we design hollow Cu2O nanospheres for durable and selective CO2RR electrolysis in producing C2H4. Our work recognizes the previously overlooked passivation reconstruction and self-stabilizing behavior and highlights the critical role of the local atmosphere in modulating reconstruction and catalytic processes.

Multi-model ensemble learning for battery state-of-health estimation:Recent advances and perspectives

引用

Journal of Energy Chemistry 2025年第1期100卷 739-759页

作者： Chuanping Lin Jun xu Delong jiang Jiayang Hou Ying Liang Zhongyue Zou xuesong Mei State Key Laboratory for Manufacturing Systems Engineering Xi'an Jiaotong University Shaanxi Key Laboratory of Intelligent Robots School of Mechanical Engineering Xi'an Jiaotong University Department of Electrical Engineering and Automation Luoyang Institute of Science and Technology School of Mechanical Engineering Hangzhou Dianzi University

The burgeoning market for lithium-ion batteries has stimulated a growing need for more reliable battery performance monitoring. Accurate state-of-health(SOH) estimation is critical for ensuring battery operational performance. Despite numerous data-driven methods reported in existing research for battery SOH estimation, these methods often exhibit inconsistent performance across different application scenarios. To address this issue and overcome the performance limitations of individual data-driven models,integrating multiple models for SOH estimation has received considerable attention. Ensemble learning(EL) typically leverages the strengths of multiple base models to achieve more robust and accurate outputs. However, the lack of a clear review of current research hinders the further development of ensemble methods in SOH estimation. Therefore, this paper comprehensively reviews multi-model ensemble learning methods for battery SOH estimation. First, existing ensemble methods are systematically categorized into 6 classes based on their combination strategies. Different realizations and underlying connections are meticulously analyzed for each category of EL methods, highlighting distinctions, innovations, and typical applications. Subsequently, these ensemble methods are comprehensively compared in terms of base models, combination strategies, and publication trends. Evaluations across 6 dimensions underscore the outstanding performance of stacking-based ensemble methods. Following this, these ensemble methods are further inspected from the perspectives of weighted ensemble and diversity, aiming to inspire potential approaches for enhancing ensemble performance. Moreover, addressing challenges such as base model selection, measuring model robustness and uncertainty, and interpretability of ensemble models in practical applications is emphasized. Finally, future research prospects are outlined, specifically noting that deep learning ensemble is poised to advance ens

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.
